PROBLEM TO BE SOLVED: To provide a method for repairing a molten metal transfer trough for improving adhesive properties of repairing monolithic refractory with a base material of a repairing position as compared with prior art. SOLUTION: In the method for repairing a molten metal transfer trough to be repaired comprising the steps of spraying a monolithic refractory to an eroded surface of the refractory lined in the trough for transferring molten metal with slag, adhering a slurry containing a mixture of a CaO source of a composition for generating Gehlenite, an Al2O3 source and an SiO2 source as remained in the state that the slag is adhered to the eroded surface of the lined refractory, and spraying the refractory thereon. |
